Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disc brake cover.

As is well known, in motorcycles, a caliper is attached via a bracket to the front fork that supports the axle of the front wheel, and a friction pad built into this caliper brakes a disc that rotates together with the axle. in six
Gometake ^ With gear brakes, pebbles, mud, etc. fly in from the front while the vehicle is running, and these can get stuck between the caliper and the disc or damage the braking surface of the disc. For this reason, some models cover the entire disc with a cover, but since this prevents wind from entering, it has poor heat dissipation properties for the braking heat generated by the friction between the disc brake's friction pad and the disc during braking, and it is also lightweight. There are problems such as not being able to achieve this.

This invention was made against the background of the above circumstances, and is designed to cover the braking surface of the disc on the front side of the fork and the upper part of the caliper with an arc-shaped cover body to improve the heat dissipation of braking heat, and to protect the disc brake from pebbles, mud, etc. The aim is to provide a disc brake cover that provides sufficient protection and is lightweight.

In order to achieve the above object, the present invention forms a cover body in an arc shape to cover a disc that rotates integrally with the axle, and attaches the cover body to the fork so as to cover the disc braking surface on the front side of the fork and the upper part of the caliper. It is characterized by being able to win.

Hereinafter, an embodiment in which the present invention is applied to a motorcycle will be described in detail with reference to the accompanying drawings.

A front fork 1 of a motorcycle is provided on the front side of a vehicle body so as to be pivotable by a handle 2. An axle 3 is fixed to an axle mounting portion 1a which is integrally formed and protrudes toward the lower end of the front fork 1 by a NAND 4, and a front wheel 5 is rotatably supported on this axle 3. A disk 7 is fixed to the hub 6 of the wheel 5 by a fixing port 8, and rotates together with the front wheel 5.

Also, the brake mounting part i is located on the rear side of the lower end of the front fork l.
b is formed in a protruding manner, and the brake holder 9 of the distub 1/-key A is attached to the brake mounting portion 1b with the tightening port io,
Fixed by io. This bracket 9 is supported by calipers 11 or support poles 1-, 2, 12. The caliper 11 straddles the disc 7 from the outer periphery,
The brake hose 1 is provided with pistons (not shown) that push friction butts arranged on both sides of the disc 7.
Actuation supplied from 3! The friction pad is adapted to come into sliding contact with all the disks 7 and perform braking.

On the front side of the lower end of the front fork 1, force l<-mounting part 1c
, lc are formed below the axle 3, and the cover mounting portions 1c and lcL are formed below the disc brake cover B.
is projected from the disc braking surface 7a on the front side of the front fork l so as to cover the upper part of the carry/<11.

As shown in FIG. 4, this disc brake cuff<-B is integrally formed of synthetic resin, and includes an arc-shaped cover body 14 that covers the braking surface 7a of the disc 7 and the upper part of the caliper, and the inner outer periphery of the front fork 1. It consists of a fork fitting part 15 that fits into the front fork 1, and a fork holding part 16 that comes into pressure contact with the outer periphery of the front fork 1.

The cover main body 14 is formed into a U-shaped cross section, and the inner covering part 14 is formed into a U-shaped cross section.
a and the outer covering part 14b cover both sides of the braking surface 7a of the disc 7, and mounting holes 14c are provided at both ends.
, 14c are provided. Further, the upper end 14d of the cover body 14 extends to cover the disc brake A from above to prevent pebbles, mud, etc. from entering. Further, the fork holding portion 16 rises from the cover main body 14 and is bent to correspond to the outer periphery of the front fork 1. A band attachment part 16a is integrally formed on the outer periphery of the fork holding part 16, and the brake hose 13 is fixed thereto.

To assemble the disc brake cover B, the cover main body 14 straddles the braking surface 7a of the disc 7 from the outer periphery and covers both sides from the front of the vehicle body, and the fork fitting part 15 is fitted to the front fork 1. And mounting holes 14 at both ends
The screws 17.17 are inserted into the screws 17.17 and 14C and screwed onto the cover mounting parts 1c and lc of the front fork 1, and the speedometer 18'+ does not become an obstacle to assembly, making the work easy. . Then, bend the central part 19 of the joining part 15 inward to the fork, and fix the fork holding part 16 to the front fork 1 by tightening it together with the brake hose 13 using the head 20. .

Next, the operation of this embodiment will be explained.

As described above, the disc brake cover A is installed from the front of the vehicle so that the cover main body 14 covers both sides of the braking surface 7a of the disc 7, and the upper and lower parts sandwich the axle 3 at the lower end of the front fork 1. Cover mounting part 1c located at
, 1cL cantilever supported for easy and reliable assembly.

The brake force /< -B is the force/ The integrated brake force 14 covers the disc braking surface 7a on the 111j side of the front fork 1 and one side of the disc brake A, and from this side, pebbles and Even if mud or the like flies into the disc brake from the front or -L direction, the surface 7a of the disc 7 will not be damaged, and the inside of the disc brake A will not be clogged with mud.

Also, while driving, add hydraulic fluid to disc brake A to 4 to 1.
Dust pa 11. At this time, even if the friction pad generates braking heat due to friction with the disc 7, the wind may blow dust onto the braking surface 7a of the disc 7 at the rear of the front fork 1, and the disc may Since it easily enters the inside of brake B, it has excellent heat dissipation properties for braking heat.

Further, since the disc brake cover B is arc-shaped and covers only the front disc braking surface 7a of the front fork l and the upper part of the disc brake B, it is lightweight and manufacturing costs can be reduced.

Note that, although the main body 14 of the disc brake cover B has a U-shaped cross section with the inner covering portion 14a shorter than the outer covering portion 14b, the present invention is not limited to this.
4a and the outer covering part 14b may be made to have the same length as the outer covering part 14b, or may be formed into a cross-sectional shape so that only the outer covering part 14b is formed.

Furthermore, the fork holding portion 16 is fixed using the aforementioned hand 20.
Alternatively, it may be fixed with bolts or the like.

Further, this disc brake cover B can be similarly applied to a vehicle equipped with a disc brake on the rear wheel.

As described above, this invention forms the main body of the disc brake cover in an arc shape and rotates integrally with the wheel, and attaches the cover main body to the fork so as to cover the disc braking surface on the front side of the fork and one side of the caliper. Because of this, the wind hits the disc at the rear of the fork while driving, and can easily enter the inside of the caliper, improving the heat dissipation of braking heat generated during braking. In addition, the disc braking surface on the front side of the fork is not sufficiently protected from damage caused by pebbles hitting the braking surface.
It effectively prevents disc brake mud from clogging, and since it covers only the disc braking surface on the front side of the fork and the upper part of the caliper, it is lightweight and reduces manufacturing costs.
